APPARATUS FOR USE IN DYEIN'G- WOUND YARN.

Specification of Letters Patent.

Patented Apr. 18, 1911.

Application filed October 5, 1909. Serial No. 521,082.

To all whomit may concern:

Be it known that I, HERMANN Rnson, Sr., a subject of the Grand Duke of Baden, and resident of Lorrach, Baden, Germany, have invented new and useful Improvements in Apparatus for Use in Dyeing Wound Yarn, of which the following is a full, clear, and exact specification.

Perforated pipes or tubes upon which roving or yarn is wound fordyemg and which are secured on holders in the ye bath are known, as also are forms ofperforated spindles on which are secured spools or cops of yarn for dyeing purposes.

- My invention consists of a perforated hollow spindle for use in dyeing wound roving or yarn, whereon is secured a spool of yarn or its erforated tube, the said spindle being provid ed in addition to the erforations, with external longitudinal and transverse grooves. By forming the spindle in this manner it is possible to fit the spool of yarn to be dyed over its entire length close to the spindle and yet obtain a uniform distribution of the dye liquor throughout. Furthermore, owing to the exact fit of the spool the spindle forms a strengthening core for the spool or spools, and affords the necessary support for them even if their tube or shell has a wall of small thickness. In order to prevent the inner layers of yarn from being sucked into the perforations of the yarn carrying tube on the spindle durin the dyeing operation, the said tube is pre erably pro- 1vllled with a porous covering of web or the In the accompanying drawing, which illustrates this invention, Figure 1 shows a spindle provided with three spools or yarn carrying tubes placed one above the other.

F1 2 shows a portion of the same in longitudinal section on a larger scale, and Fig. 3 shows a transverse section of Fig. 2.

Into the false bottom a of a dye vat is screwed a erforated pipe or hollow s indle b which fiirms the spindle on whic the roving or yarn is placed and a number of which pipes or spindles may of course be provided. On this hollow spindle b are placed the perforated spools or tubes 0 provided with the yarn and laced one above the other. The said spoo s or yarn carrying tubes 0 which may be 'of thin sheet metal have an inner diameter correspondingto the outer diameter of the spindle b so that they lit close to the latter and are supported by it, the thick walled spindle 12 forming a strengthening core for the spool or tube 0 and givin it the necessary support. In order to al ow for the proper distribution of the dye liquor in spite of the close fit of the spool or tube a on the s indle b, the said spindle is provided in a dition to its perforations h, with lon 'tudinal grooves e and transverse grooves vz (Figs. 2 and 3) by means of which a uniform distribution of the bath through the yarn is obtained in all directions and throu bout the whole length. A joint is elfecte between the spools placed above each other by means of packin rings f, as shown in Fig. 2, and the spindle b is closed at the top by means of a screw cover 9, as shown in F1 1. After removing the s 001 or tube a w1th the dyed yarn thereon rom the spindle b, itis ad. vantageous for the purpose of drying in centrifugal apparatus to introduce a wooden core into the s 001 or yarn carrying tube.

Owing to t e spools of yarn carrying tubes 0 being fitted closely on a core spindle or newel during the dyeing they can be made of a very thin wall, so that the are of great lightness, which is of considerable advantage .for their fixing on the carrier of fliers.

What I claim is:

1. A hollow column for use in dye vats comprising a hollow perforated spindle, a series of superposed perforated spools carried by said spindle, packingrings connecting said spools, the exterior of said spindle being grooved annularly and axially, said spin le being screw-threaded on its lower end, and an angular cap at the top of said spindle, substantially as described.

2. A ollow column for use in d e vats, compris ng a hollow perforated spindle, a

series of superposed perforated spools car-- my name this 18th day of September. 1909,

ried by said spmdle, packing ijfings connegtin the presence of two subscribing witnesses. ing said spools the exterior 0 said spin le being grooved annularly and axially, said HERMANN RESCH SENIOR 5 spindle having fastening means on its lower Witnesses: end, substantially as described.
